Which Autohelm Unit is this? I have recently installed an ST 4000+MK2. As long as we are on this topic, is it normal for the Raymarine fluxgate compass to constantly vary its reported heading +/- 3 degrees from the magnetic compass heading even when the boat is tied securely to a wall in calm conditions with no moving, rolling, pitching or yawing. No one is down below moving large iron masses, the engine is not running and all other electrical or electronic equipment is off. If this message is too far off topic, I apologize.

We have found the best way to steer downwind flying a spinnaker, or with the headsail out on the end of a whisker pole on the side opposite the main (goosewinged) is with one person not at the helm but with a finger poised over the unit feeding in one degree correction changes as necessary.
